Cu, Ag, Au; Figs. 210 - 228, Tables 25 - 26

This chapter discusses photoemission and inverse photoemission of group IB (noble metals) like copper (Cu), silver (Ag) and gold (Au), particularly Cu and Ag. Inverse photoemission spectra from (100) surface, (110) surface and (111) surface of Cu are shown in figure. Dispersion of the surface states on the (111) surface of the Cu is illustrated. Ag has a face-centered cubic (fcc) crystal structure with a lattice constant of 4.09 Å (at T = 300K). Binding energies of occupied and unoccupied surfaces states on Ag surfaces are tabulated. Angle-resolved photoemission spectra from the (100) surface, (110) surface and (111) surface of Ag are recorded. Inverse photoemission spectra from the (110) surface of Ag are illustrated.
